'tial' section thehub member Fig. 3 shows in side elevation, and parofierried by the ifxl'e and to which the spokec ,rrimg'rnembet is detachably secured, the sectioned parts being shown in section on the line Fig- 4.- shows in 'vjegtjoai' section and-in g gghed position the spoke carrying niember 't vith the in lace.

ig. 5 is a face view of the member shown in Fig. 8.

1 indicates the spokes usually and pref erabl madeof metal tubes secured by weldmg or other means at their outer ends to the metal rim 2. The latter is shown within an annular recess in the vertical face of the member 3. hen the two-members are clamped together as'shown in Fig. 1. a

strong and firmconnection is established-by which power may be effectively transn'iitted the periphery of member 4 preferably, and if desired the inner ends of the spokes 1 may be of-such length as to seat directly upon the periphery of me in Fig. 1,-they are shows; as slightly sep-' arated therefrom.

For tastening the two sections together. esmade in the usual way from metal having any desired means may be employed as for clencher adapted to secure an ord1- i spokes carried by and socketed .inthe parts by which it is fastened demountable meri1ber'3. Member3 fits upon mber 4 although,

nstance a nut 8 having an internal thread adapted to engage an external thread 9 upon the end of, the hub barrel extending outward and preferably formed integrally with member 4 and in addition a hub cap or locking nut 10 having a reverse screw' thread 11 adapted to engage an external reverse screw thread 12 upon the extreme end ofgthe hub member' i. in placeof these'usual ex pedien'ts" other means may be employed;

\vhereby'the member 3 fitting upon the cylindrical portion of the member 4 may be other desired means. 7 I v 7 As Wlll beunderstood, the inner portions of the spokes 1 may be fastenedagamst raclamped against the face thereof by any dial movement in their sockets by rivets 20 or otherwise if desired, although this is not necessary to the main purposeof my invention; x

The sockets for t-heends of. the spokes within the member 3 as well as,t he dr1ving 4 concavities 7 may be formed in any desired way but are preferably provided in an expeditious manner by clamping the members 3 andfl together and boring radial holes therein of the same sizeas the spoke tubes. After this operation when the two'membeis are so arated the socketsin the member 3 as wel as the concavities 7 of the member'4 so formed assure accurate and positive fit of thwarts p.

at I claim as my invention 1s:'--

1-. A demountable' metal wheel having a separable hubrmemberin which the spokes are mounted to leave their inner ends ex-' tending radially inward -fromthe .point'of mounting comblned with the complementary hub member having upon lts face grooves or ooncavities to adapt said complementary hub member to fit partially around and form interlocking engagement with the sides of the exposed ends of said spokes when the demountable' member is locked in osition against the complementar hub mem r.

2. In a separable or temountable metal wheel, .aseparable hub member having spokes projecting radially inward there-- through and demountably fitted directly upon the hub barrel and a complementary hub member having radially extending grooves or' notches formed in the face thereof embracing the sides of the project 'ing inner endsof the spokes when the two members are clamped together.

3. In a separable metal vwheel, the coma clamping the two members together with the sides of the -engagedin 'said" bination of'a hub member having radially ext wling sockets through which the inner end if the spokes project radially in'wa rd to expose the sides of the spokes and a complementary hub member having a flange pro vided with radially' extending concavities on the face thereof to interlock with the sides.

of the projecting inner ends of the spokes when the two members are fastened together.

4. In a metal wheel, the combination with a separable hub member provided with a socketed flange in which the spokes are socketed and through which their ends extend radially inward to expose'the sides'ofl the s 'iokesbelow the sockets and "a comple-i. n'ientary hub member fittmgf an annular.

groove in theface of the -:sepmm hub member and having radially extendihg'ooncavities formed in the face thereof to inter lock 'with the exposed si has of the inner ends of the spokes. I

5. In ademountable wheel; th'e' 'combination witha separable hulunember in'wlnch the spokes are socketed with their inner ends exposed, of a complen'ientary hub in'ei'nbe'r having an integral flange provided-hvith notches or grooves in a vertical face thereof to receive and fit around theisides ofthe ex;

face thereof to receive the inner ends of the socketed spokes and means for sepa'rably notches. ,i V 7. In a wheel, the combination of two hub interlocking with theother mer'nberwhen the two hub sections are secured t0gether1,
